Be it known that I, JAMEsA, DWYER, a citizen of the Unitedjstates, residing at 'Blackwelh'in the countyof Kay and State.

of Oklahoma, have invented new "and useful Improvements in Extricatin'g, Devices, of which the following isa specification.

My present invention has: reference toa means whereby a mired vehicle may, through its own power, extricate itself from A further object is the provision of sim-i ple means for this purpose inztheenature of and which may be rigidly secured on the 20 stump, pole or other support, or which end a pulley, which may be conveniently car ried 1n the car when not required for use,

hub of the power wheel of a mired vehicle, the ,said pulley designed to have wound therearound and secured thereto a cable whose outer end is directly connected to a may be trained around a pulley on such support and attached to the front of the vehicle, and whereby the turning of the shaft in the heads of the bolts .5 that pass through.

will wind the cable on the pulley and draw the machine out of the'rut,

The drawings which accompany and form part of this application, illustrate a satis' factory embodiment of' the improvement,- and wherein: Figure l-is a rear elevation of theimprovement.

Figure 2 1s a central transverse sectlonal now through the lmprovem'ent, showing the same arranged upon the hub of the power shaft of an automobile.

Figure 3 is a front elevation of the im-' p rovement. 1

My improvement is comparatively small,"

so that the same can be conveniently arranged under the seat or stored in any convenient place in an automobile. The cable employed in connection withthe pulley of the improvement, may b e v usedvfor hauling disabled vehicles when not arranged around the pulley and is'therefore also of such sue to be conveniently stored in the vehicle.

The improvement, as above stated, is in the nature of a pulley and is indicated by the numeral 1; The pulley has its inner face formed with a flange 2 that is thicker than its outer flange 3, and the said'flange. 2 is provided with spaced circumferentially arranged depressions 4, corresponding in number and of a size to snugly receive there- 1 cable on the pulley,

the flange '6 of'the 111113271 and jsecure" thesa-me Y i on the wheel. 'Thebodyv of (the, pulley 1, from its inner face,is providedwi'th a socket 8 shapedto correspond with the shape of an opening 9 that communicates with its bore 8. In this opening there isreceiveld a sleeve 10 which may be of harder metal than that of the pulley, 1. Also-received in the a sleeve 10 and having its inner and socket,

end- 11 threadedly engaging the threaded memberxhas its outer-end provided with exterior threads and these threadsare en-pprojection 12 onjthe axle -13 of the automo-u fi v bile there is ,a'bolt "memberlt. .Thebolt gaged by a locking washer 15 which contacts with both thefouter vend of the sleeve 10v and the pulley =1. Byscrewing. the nut 15 home on the bolt 14, the pulleyf will be, forced against thehub flange 6iso that the bolt head's-5 will be not only received in but I by the depressions 4. H

forced in contact with the walls provided t I SO The operationof the improvement is well known to those skilled infthe art to which such inventions relate, a cable, being fixed on j v the pulley and secured to a stationary ob-f' and thereby'draw they- 4 ject, and the engine is started to wind the machine out of' a rut.

,Having clescrib edthe invention, I claim V 1.' AT means' for extricating automobiles from ruts, in whichthe hub cap and the sustaining nuts have-been "removed respectivelyfrom the hub andaxle of a dr-ive wheelof an vautomobile;saidmeans,comprising a pulley havingits inner face 'formed with" circumferential depressions to receive 1 therein the .heads of the bolts ofqthe hub flange andhaving a central depression toreceive the projecting. end of the hub therethereto, i

a 2. A means for extricating mired automobiles, in-which the hub cap and the drive; axle securing nuts are removed, said means comprising a pulley having itsinner fl g i 6O the projecting portio'n'; of" the hub 7, The body 1 of thepulley iscentrally-[formedwith thickened and its inner face vprovided with spaced depressions to receive the heads of the hub flange securing means therein, said pulley having atbore entering from its, inner face and corresponding in shape to the projecting portlon' of the hub and receiving the said portion of the hub therein, Saidpulley having a centralopening in which is received the projecting and threaded end of 2:.) the drive shaft of'the automobile, a Sleeve ion-said ogening, a bolt having an inner threaded ojre received in the sleeve and screwed onthe threaded endv of the axle,

said bolt having its outer end 'exteriorly threaded end projecting beyond the pulley, and a binding nut screwed thereon to contact With the outer end of the sleeve and
